Insulin-like growth factor (IGF) family

Insulin-like growth factor is a family of proteins with a similar structure to insulin. This family includes ligands and insulin, receptors and insulin receptor, and IGF-binding proteins. It plays important roles in differentiation, cellular metabolism, proliferation, apoptosis and transformation.

Our insulin-like growth factor range includes human, bovine, porcine IGF-1 protein used in the maintenance of human pluripotent stem cells and necessary for cell growth in the absence of insulin. We also offer a synthetic analog form of IGF-1, insulin-like growth factor long arginine 3, which has improved biological potency and extended half-life.

Qkine robust animal-free manufacturing platform, along with rigorous quality control procedures, ensure that all our insulin-like growth factors are:

• animal origin-free (AOF) and carrier protein-free
• highly pure (>98%, by SDS-PAGE quantitative densitometry)
• highly bioactive (equally or more bioactive than other dominant suppliers) and come with our Bioactivity Guarantee
• highly reproducible with excellent lot-to-lot consistency

Qkine is committed to manufacturing bioactive proteins of the highest quality to enhance scientific outcomes and improve reproducibility. All our products rigorously adhere to the Nine-point Qkine Quality Commitment.
